Bug: Ballast tanks fail to fill

Version: Latest Beta Release
Description: Opening the for and aft ballast tanks triggers the "flooding" sounds however the tanks never start filling. The "flooding" noise continues forever without any change in pitch that is associated with the tanks gradually filling.

Ballast tank gauges show empty for the duration. Flooding the negative boyancy tank also has no effect.

Not yet confirmed this, but it appears bug occurs only once the boat has previously submerged successfully. i.e The first time runs as planned, its only once you have returned to the surface and try to submerge once more that the big appears.

Can you reproduce it?

What is the level of the trim tank?

Its happened twice, but not under the kind of controlled conditions I'd want to call it reproducable. Neither did i take the time to carefully note the levels of the trim tanks, however to the best of my recollection they had only minor changes if any.

I'll run through some iterative testing and report back.

On a side note, if this was caused by something like too much positive boyancy, should there perhaps be an audable symptom such as the tank flooding noise tailing off (as opposed to the deepening slosh-and-thump of a successfully flooded tank) to indicate that without the boat starting to sink, the flooding also slows to a halt?

Yes, you are right, if the sound fx indicate full tanks but the gauges and buoyancy behavior suggest otherwise, we would like to know how to recreate that and solve it. thanks
